Abstract

The embodiment of the invention discloses a pattern etching method for a double-glass photovoltaic module. The method comprises the following steps of: applying a film onto a glass substrate of the double-glass photovoltaic module and forming a film-coated surface; arranging a mask layer with a preset hollow pattern on the film-coated surface; taking the mask layer as a shielding body, and performing etching treatment on the film-coated surface; and taking down the mask layer, and cleaning the glass substrate. The method of the embodiment of the invention has the advantages of easiness in batch production, simple manufacturing equipment, and higher processing speed.

Description

technical field [0001] The invention relates to a method for pattern etching, in particular to a method for pattern etching of a double-glass photovoltaic module. Background technique [0002] Double-glass modules have become mainstream photovoltaic products. The rise of BIPV puts forward more requirements for building material properties, especially appearance. In order to meet this requirement, the double-glass photovoltaic modules have produced a variety of colorful products by using methods such as colored film and patterned film. For thin-film components, laser or ultra-thin absorbing layer technologies are used to prepare light-transmitting products. [0003] For double-glass photovoltaic products with a top-lined structure, since the substrate is the sunny side, it is difficult to optimize the color appearance and pattern the appearance, so the appearance of the product has always been relatively simple. If the glass surface coating technology is used, the coating ...
